Do you have any clips of the exhaust driving it conservatively in street mode? I'm kind of curious to see it would sound like in real world driving around town.
Sounds awesome in the clips you provided, but while I can definitely tell the difference in tone between the valves open/closed, its hard to gauge what the difference in volume is.
And also, I'm guessing with the tips being adjustable, this should fit an E90 with the tips not sticking out more than stock?
Looks like a great product.
